| Subject: CVE-2023-52525: wifi: mwifiex: Fix oob check condition in mwifiex_process_rx_packet |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: mwifiex: Fix oob check condition in mwifiex_process_rx_packet |
| |
| Only skip the code path trying to access the rfc1042 headers when the |
| buffer is too small, so the driver can still process packets without |
| rfc1042 headers. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52525 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
